YNV05T100xy DC-DC Converter Family Data Sheet
3.0-5.5 VDC Input; 0.9-3.3 VDC Output @ 10A
varied between 25 °C and 85 °C, with airflow rates
from 30 to 500 LFM (0.15 m/s to 2.5 m/s), and
vertical and horizontal converter mounting. The
airflow during the testing is parallel to the long axis
of the converter, going from ON/OFF pin to output
pins.
For each set of conditions, the maximum load
current was defined as the lowest of:
(i) The output current at which any MOSFET
temperature does not exceed a maximum
specified temperature (120 °C) as indicated by the
thermographic image, or
(ii) The maximum current rating of the converter
(10 A)
During normal operation, derating curves with
maximum FET temperature less than or equal to
120 °C should not be exceeded. Temperature on
the PCB at the thermocouple locations shown in
Fig. G should not exceed 120 °C in order to
operate inside the derating curves.
Efficiency
Fig. x.3 show the efficiency vs. load current plot for
ambient temperature of 25 C, airflow rate of 200
LFM (1 m/s) and input voltages of 4.5 V, 5.0 V,
and 5.5 V.
Fig. x.4 show the efficiency vs. load current plot for
ambient temperature of 25 C, airflow rate of 200
LFM (1 m/s) and input voltages of 3.0 V, 3.3 V,
and 3.6 V for output voltages
≤ 2.5 V.
Power Dissipation
Fig. 3.3V.4 shows the power dissipation vs. load
current plot for Ta = 25 C, airflow rate of 200 LFM
(1 m/s) with vertical mounting and input voltages
of 4.5 V, 5.0 V, and 5.5 V for 3.3 V output voltage.
Start-up
Output voltage waveforms, during the turn-on
transient with application of Vin at full rated load
current (resistive load) are shown with 47
μF
external load capacitance at Vin = 5 V in Fig. x.5.
Ripple and Noise
The output voltage ripple waveform is measured at
full rated load current. Note that all output voltage
waveforms are measured across a 1
μF ceramic
capacitor.
The output voltage ripple and input reflected ripple
current waveforms are obtained using the test
setup shown in Fig. H.
